Frosty Mug runs the premiere (and only) watering hole in Ponyville. He's been behind the pine for years, and listened to many a sob story, and joyous announcement. Enjoy his recollections of a rather strange week in which he served a different Element of Harmony every day, and a pony he would have never thought he'd have the honor of getting drunk. These are the memoirs of a Ponyville booze vendor.

Now with bonus drinks! Consider it 'Happy Hour'!

Twilight Sparkle is a gifted student and scholar. When she attempts to harness her creative side by writing a science-themed sensual romance novel, however, things rapidly get out of hoof. Can her friends stage an intervention before she humiliates herself (and them) at a prestigious literature recital?

No. No, they cannot.

The royal court of Canterlot welcomes its newest member with open forelegs: the human philosopher Voltaire, from Earth.

On Earth, Voltaire is known as the greatest enemy of tyranny in the history of literature, and a legend in his own mind.

On Equestria, the court betting pool is giving him a week before the Princess banishes him to the Moon.

Note: This story doesn't have sequels per se, but there are a couple of short follow-ups set in the present day ("Parade Coverage" and "Secret Histories"), and a prequel of sorts in "At the Inn of the Prancing Pony".

There really is no excuse for forgetting something as important as a hoof-written law. But Celestia forgot. And now, a thousand years after she wrote it, a law comes into play mandating that Celestia take a two-month sabbatical from her duties as Princess of Equestria.

So what happens when she has to step down for a couple months and leave Luna by herself in the bloody gladiator ring that is Equestrian politics? What happens when Celestia has to disguise herself and mingle with the populace of Ponyville without them knowing?

The short answer to that would be "a string of hilarious chance encounters, sisterly banter, romantic mishaps, and a political coup that was decades in the making."

The long answer, of course, is this story.

This story is a sequel to From the Mouths of Fillies

Dinky and Sparkler have the most awesome godmom in Equestria--that's right, me! Rainbow Dash. Being friends with their mom means I've spent a lot of time with them over the past few years. They're pretty cool kids.

But then ... well, Ditzy got sick. Like, really sick. I've been watching them for her, but if she doesn't get better soon, they may be staying with me for a lot longer than I thought.

That's okay, though: I'm Rainbow Dash. I can handle anything life throws at me.

(Connected to From the Mouths of Fillies, Saying Goodbye, and Feeling Regrets)

Twilight Sparkle thinks that Cheerilee would provide a very interesting partner... to talk to... about literature. Nothing else. Right?

Mood Wings - Observations on Pegasus Body Language.
